Wiper WPM 44,45x53,97x4,76/7,1 NBR+Stal

The WPM type scraper ring is designed to protect the glands of hydraulic cylinders from external contaminants.
It prevents mud, water, and dirt from entering the system, protecting the seals and the surface of the piston rod from accelerated wear.

Construction and operation:
The scraper is made of oil-resistant NBR rubber, set in a steel frame that ensures a secure and durable seating in the housing.
The construction is designed to be press-fitted into the assembly, ensuring a strong hold even under intense working conditions.
The flexible rubber lip closely adheres to the piston rod surface, effectively cleaning it of dirt and moisture during the cylinder's working movement.

Applications:
hydraulic cylinder glands,
working mechanisms of construction and agricultural machinery,
systems exposed to mud, dust, and water.

Materials:
working part: NBR (nitrile rubber) – resistance to oils and greases,
housing: steel – provides rigidity and secure fixation.
